Well, after looking at your pics, I decided to give this kit another try.

I was worried about heat and the fact that the kit has a cooling fan.
But after hours of running the kit in a controlled environment, the
leds do get hot but not enough to cause damage.
Plus Marc's design dissipates the heat to the back of the kit (away from he angel eye tips) where the heatsink and cooling fan are.
Even if the fan was to fail, the leds do not seem to produce enough heat
to threaten the angel eye tips.
I guess time will tell.

This time, I followed the directions.
and the angel eye cover closed properly without much effort.
